Two music files that are identical can sound different coming from Tidal, Qobuz and all other streaming services simply due to factors like different audio compression methods (codecs), bit rates, digital signal processing (DSP), and volume normalization, all of which can alter the original sound. Different services use different formats and processing techniques to balance sound quality with bandwidth and storage efficiency. Other factors include; Device and app settings, Network and buffering and Mastering and loudness. So, it doesn’t matter if it’s two music files that are identical, or a 1000 music files that are identical. As previously stated, it’s how the original, identical music files are implemented that makes them sound different. I understand that you’re perhaps attempting to convey some kind of profound concept. However, the answer to your question is really quite elementary. Whether you accept the facts is entirely up to you. Happy listening.
